7. Engine Ground Test Record
WARNING: DO NOT STAND WITHIN THE DANGER AREA OF THE PROPELLER.
THE PROPELLER CAN CAUSE DEATH OR INJURY TO PERSONS.
WARNING: YOU MUST MAKE SURE THAT THE ENGINE IS SAFE BEFORE YOU
TURN THE PROPELLER. DISCONNECT THE SPARK PLUG LEADS.
MAKE SURE THAT:
- THE IGNITION SWITCH IS IN THE “OFF” POSITION.
- THE “P” LEADS ARE GROUNDED.
- THE THROTTLE IS SET TO “CLOSED”.
- THE MIXTURE CONTROL IS SET TO “LEAN CUT-OFF”.
WARNING: DO NOT GET OIL ON YOU. OIL CAN CAUSE SKIN DISEASE.
WARNING: DO NOT GET FUEL ON YOU. FUEL CAN CAUSE SKIN DISEASE. DO
NOT ALLOW FIRE NEAR FUEL. FIRE BURNS AND CAN CAUSE
INJURY TO PEOPLE AND DAMAGE TO EQUIPMENT.
WARNING: WHEN YOU COMPLETE AN INSPECTION, MAKE SURE THAT YOU
REMOVE ALL LOOSE ITEMS/TOOLS FROM THAT AREA. LOOSE
ITEMS/TOOLS CAN PREVENT FULL MOVEMENT OF THE AIRPLANE
CONTROLS. THIS CAN CAUSE DEATH OR INJURY TO PERSONS.
CAUTION: YOU MUST ATTACH BLANKS/CAPS TO HOLES/PIPES WHEN YOU
REMOVE COMPONENTS. IF YOU DO NOT DO THIS, UNWANTED
DEBRIS CAN ENTER THE HOLES/PIPES. THIS CAN CAUSE
BLOCKAGE TO THE AIRPLANE SYSTEMS.

System Check Result
Note: The Idle RPM and the ground static Max RPM specifications are different
from the TCM IO-240-B engine Maintenance Manual specifications. This is
because of the engine to propeller installation in the DA20-C1. Refer to
Chapter 71-00 for data.
Note: Set the engine mixture control to Full Rich to do the engine checks unless
you are told differently.
CAUTION: BEFORE YOU RUN THE ENGINE AT MORE THAN 1800 RPM MAKE
SURE THE OIL TEMPERATURE HAS RISEN TO 24°C/75°F. AND
THE CHT HAS RISEN TO 93°C/200°F. THIS WILL PREVENT
POSSIBLE DAMAGE/TOO MUCH WEAR TO THE ENGINE.
Start The Engine.
Set engine RPM to 1700 for sufficient time to do these checks:
− Record Fuel Pressure.
− Record RPM drop for each magneto.
(Limit: Not more than 50 RPM drop difference,
with a maximum RPM drop of 150 RPM for each magneto).
Set engine RPM to Full Power for sufficient time to do these checks:
− Record Fuel Pressure.
− Record Oil Pressure.
− Record Oil Temperature.
− Record Cylinder Head Temperature (CHT).
− Record Alternator/Generator Output.
− Record Full Power RPM.

System Check Result
CAUTION: THE MAGNETO OFF CHECK MUST BE DONE AT IDLE RPM. THIS
WILL PREVENT DAMAGE TO THE ENGINE.
CAUTION: DO NOT SHUT THE ENGINE DOWN UNTIL THE CHT GOES
BELOW 149°C /300°F.
Note: For the fuel injection system inspection the IDLE RPM setting for the
IO-240-B engine installed in the DA20-C1 is 1000 ± 25 RPM.
- Refer to the TCM Service Information Directive SID97-3C or later approved
revision.
Set engine RPM to IDLE.
− Record IDLE RPM.
− Record Fuel Pressure.
− Record Oil Pressure.
− Record Oil Temperature.
Set the Ignition switch to OFF for a short time. Then set the Ignition switch to BOTH. If the engine
continues to run when the ignition switch is set to OFF, refer to TCM Maintenance Manual Chapter
12.
Set the engine mixture control to LEAN/CUT OFF.
− Do a mixture RPM rise check. (Limit: 25 - 50 RPM)
− Do a positive Fuel Cutoff (manifold valve) check.
When the propeller stops rotating:
− Set the ignition switch to OFF.
− Set the master switch to OFF.
